What other features does SpoofCard offer?
You have the ability to change your voice to a Male or Female. If you do choose to change your voice, the person whom you call will hear your transformed voice in real-time. We also offer the option to record your conversation, which can later be retrieved by logging-in to the control panel or calling the toll-free access number from any phone. There is no extra cost for these features and they are included with your purchase.
